What kind of camera do I need to capture deep space images?Today, on universetoday.com, there was a link to an image that is probably among the very best possible without digital alterations: flickr.com/photos/67234957@N06/6308631822/in/… clearly shows the milky way's central structures and was taken with a Canon 550d at 25 second exposure at 17mm, f3.5, ISO 3200. The electricity pole (lower right in the image) hints that the photographer was not too far in the wilderness. Note the "trick" with the hilly horizon: This removes a lot of possible light pollution from your immediate zenith view.
